@Jake Lo


The result still same, it might be the setting inside the clover

I replace with my EFI Mojave all is working but hdmi, once the cable plugged in can display external but blank for laptop display, it like the signal is lost to the internal display. Even if hdmi disconnected, the internal display still blank & causing crash

My another 3480 with Mojave is working fine with same EFI

Is it possible for you to tweak my Mojave EFI so it would works with High Sierra?
